Home Theater Project

For your viewing pleasure, Nas Man.:thumbsup:

I know, at least, I can count on you to view the pix, LOL.:)

Detailed explanation, coming this weekend, of what all I did between my previous post and now.:cool:

Okay, so we're about to finish the electronics enclosure for the PS, the stereo receiver, and the amplifier. Might even have the thing all done tomorrow. We put an elaborate series of holes on the front and back panels so the electronics can breathe.

Right now, the 1200/1v3 is being fed by the TDK GEN 15-220. To my relief, it works wonderfully. I'm using my DirectTV modem's right channel audio RCA output with my Y adapter to split the signal going into my AudioControl line driver. The line driver does quite a nice job, actually, of raising the preamplifier output voltage floor going to the 1200/1v3. Home audio has high impedance/low voltage preamps while car audio has low impedance/high voltage preamps, so I'm glad I got the line driver early on. I've noticed the REA XX 12 v2 D4's surround is a little on the stiff-side right now. This is actually the first time I'm breaking in a subwoofer at home; I guess I had never noticed the fine resonance the new NBR surrounds' add in lieu of the road noise in my car. Can't wait until it's fully broken-in. Although, I still stand by what I said in my Early Summer Project thread. No need to do low power for a bogus period of time as long as one isn't clipping the output. Also, I decided against kerfing a 5 inch port and went ahead and bought a 3 inch ID Precision Sound Aero from Parts Express. In all honesty, I find it hard to take those suggested rules for port area too seriously. Seriously, if one literally follows those rules for an aeroport's area, they're pretty much stuck with tuning in the 30s or 40s or, otherwise, have the port sticking outside of the enclosure. 6 squares for every one cube just seems very obsessive compulsive (OC) even to me, and I have autism, LOL.

I really don't even see the need to buy a SVS PB13 Ultra anymore. With my power supply's potential having a ceiling up to 15VDC, my amp always receives a healthy input voltage. Even with 10ADC transients, our RV starts sounding like a concert hall, LOL. That translates to approximately 1AAC draw on the line side. That said, I don't understand why so many guys have an objection to AC/DC conversion. Hmmm, I suppose its important for them to have their trivial opinions because they can't escape the fact that they're henpecked. Their little head does the thinking for their big head. "The wife wants me to get rid of this", "The wife doesn't approve of my hobbies", "Have to sell the system for room for strollers; got kiddos coming". Sh*t, I mean come on, if I had a nickel for every time I hear that nonsense, I'd be a damn millionaire by now. Why is it beyond a person's capacity anymore to just keep it in their pants? But, then again, I have autism, I suppose I can't empathize with neurotypicals, right? LOL:devil:

“I know so little about Facebook. But my initial reaction is strongly negative because the little that I do know suggests that Facebook is mainly a place where adolescents (of any age) post narcissistic self-advertisements in an attempt to make friends via the Internet.” -Ted Kaczynski

ROTFFL, Amen Ted. Adolescents and neurotypical adults alike who attribute not the faintest bit of independent thought and originality and absentmindedly follow around the shepard. People that think nothing of putting a metaphorical price tag on their dignity while cyber-prostituting themselves and their personal life. But, then again, what's 'dignity' if one gender can use their body as an instrument of manipulation?

Anyway, interesting article. I wouldn't be surprised if Ted is on the spectrum; brilliant minds think alike.

^^^That's a link to my system playing Official Bass Tester for Subwoofers from Ear Software. In hindsight, I should have turned off the air conditioning during the recording, but I couldn't justify it since it's been 80 plus degrees here. Like I said before, videos will be sparse and reading that article about Ted made me realize just how much of a waste of time social media is. It perplexes certain people on the spectrum, like myself, that constantly engaging in something as meaningless as staring at a monitor ever became 'a thing'. Some moron about 20 miles west of me walked off a cliff because he was absentmindedly staring at his smartphone and not paying any attention to where he was going. All the more reason for me to not even bother socializing with anybody from my generation...

I'll post some new pix either today or the next couple days.

Don't count on an atheist to spell 'shepherd' right, LOL.

Here's some pix of what I've called my Car Audio IMAX.

It may very well be a WAG (Wild Ass Guess), but I've designed the Phantom Wedge and it's currently under construction. The 'Compound' in WinISD is actually some Isobaric setting I've come to find out, so this alignment won't have much in the way of peak output. The alignment will have good low frequency extension, however, and that's more along the lines of my objective. The enclosure will be 8.3 cubes net. Also, I've grown tired of incorporating slot ports into my design; they have always been a major pain in the a$$ for my dad and I. The glue we've used in the past is the All Purpose Gorilla Glue; the problem is the stuff develops a plethora of air pockets as its curing. They always seem to collapse in the port area after the enclosure becomes pressurized making for an inaccessible leak once the thing is carpeted. Plus, it's also a pain to have to monitor and set the port walls, along with the rest of the enclosure, in the dados when we do the final assembly. IMHO, dealing with some port noise from a lack of port area from the aeroports is a lot more tolerable than having to design the stupid slot ports and hold them in place during final assembly.

The aeroports will have their own baffle that sits on top of the front baffle with a rubber gasket in between. One baffle will be accommodating a 6 inch diameter aeroport that is 12 inches long for a 23 Hz tuning. For times when I really want deep infrasonics, I'll swap in a baffle that accommodates a 4 inch diameter port that is 12 inches long for a 16 Hz tuning.

The front baffle will be kept separate from the rest of the enclosure until I know what the woofer mount cutout diameter will be. I figured my father and I should beat the heat (since it is, already, 80 plus degrees in February) in the likely (or unlikely, LOL) event the JLA 12W7v2-3 get released some intermediate time this year possibly independent of the CES debuts.

Anyway, here's the pix.

Hey, lemme pitch this as a Geico Commercial.

If you're a neurotypical, you pick the autistic guy as your scapegoat for breakdowns in communication and any other conceivable conflict. It's what you do.

For those who want to save 15% or more on car insurance, you switch to Geico. (TM)

LOL.

^^^Just as pronounced in CE as it is in IT, especially in places like SoCal. Although, that should not come as a surprise; humanity is inherently idiosyncratic. Some asinine bureaucrat (redundant?) at some point in the 20th century wanted to locate Israel in Syria to preserve the historical location while absentmindedly ignoring the fact that this was a Molotov Cocktail waiting to explode. Now, in its aftermath, we not only have September 11th, but every time a person with Asperger's goes through a TSA checkpoint, we're suspected as being a terrorist by a bunch of poorly educated morons all on account of some absentminded imbecile's rash decision, long ago.

But lets go back to STEM; what the hell has the industry produced in the way of meaningful alternate power sources in the past 70 years? Nothing, oh wait ... the antiquated solar and wind power generators and the meaningless 'refinements' of such. MIT grad students can't even replicate Tesla's work because they, like everyone else in the world, have this overt preoccupation with their social and sex lives that clouds their cognizance and technical acumen. Again, not surprising since the school promotes gambling among their math and science students. From my observations, when you look across all the disciplines for meaningful contributions to humanity, it reflects this f*cking juvenile fixation on all-things-computer. Stephen Hawking warned us long ago about the consequences with this intense preoccupation with AI. But, hey, what credibility does a disabled person have in a world full of prejudice and wrought with inherent idiosyncrasies.

Did the glue up yesterday; used Gorilla Wood Glue this time for the most part. We used sanded birch for this wedge so the dados were a little messy. Only place we used the All Purpose glue was in the dado on the top that accommodates the back. The back is inclined at about one radian (or 57degs = 180 / 3.14) to deflect the load preventing direct loading on the back of the diaphragm causing superfluous oscillations (same principle I used in the Res Wedge and the 12W6v3-D4 enclosures). The back needed an expanding adhesive since the dados were a bit deeper in certain areas than others in the top piece.

The acrylic window will be set in the right side of the wedge as this system will be used only for HT Duty. It will be sitting unused collecting dust for perhaps a couple months, a few months, or several months, LOL. Once the 12W7v2-3's are available, I'll pick up the aeros' from Parts Express. Also, we're keeping the front baffle separate from the enclosure for obvious reasons for now. Once the units are available, my father and I will stain the front baffle and apply some clear coat to show off the nice grains in the birch while the rest of the enclosure will be in the standard charcoal grey I usually use. On the inside will simply be the birch, itself, as to better reflect the LED light inside whenever I want to illuminate the enclosure and its contents. My feeling is I probably will just need the one 1200/1v3 wired down to 1.5 omegas. I have some nice 12V fans built into my electronics cabinet so I don't foresee any heat development occurring at that impedance. Although, I do have 231A DC on tap to cover the RMS if I ever decided to expand the system in the future. Then, all I would need is a good cap to cover the transients. Otherwise on some transients the automatic X-over will switch the CV to CC and will trigger the voltage protection on the amp.

At any rate, got myself some THX certified vibes from the Res XX for now, LOL. Not enough O's in the word smooth to describe the RE's output.:cool:

Anyway, I'll upload some pix 2morrow

Some dry-fit pix...

The iso in this has some visible wires over the enclosure. The HK 3770 is currently getting serviced; may have been a minor manufacturing defect, but after a while I wasn't getting output from the Klipsch floorstanders. The wiring diagram was very vague; in retrospect the stereo may have developed an impedance issue so that could be a possibility. The dumb manual presumes each floorstander is 16 omegas; if I interpreted it right. For a while, I had thought each one in the schematic implied 8 omegas; live & learn, I guess, LOL. Anyway, to make a long story short, I needed to temporarily run a ground to the TV to isolate the loop noise.

Anyway, here's the pix I promised.

Finally gonna get a piece of tha Pi.:p

Buying a Stinger 10F cap tonight. I got the system fused in the distrib block and have a circuit breaker further down the power wire, but somehow I still manage to exceed the 100A current limit and activate the CV/CC X-Over when I listen to things like Waka Flocka, Ear Software, and Bass Mechanics. Time to give the power supply a lil help with the transients.

Sh*t, just has been a rough week at work. I'm always on edge thinking I'll lose my job. The harsh reality is autistic people, like myself, are the least employable people in this country for reasons I find rather stupid. The f*cking retrograde psychoanalytical eye contact and body language garbage that certain sheeple take WAY to seriously when conducting interviews. Irony is, they'll more readily hire some innumerate neurotypical that's merely efficient with navigating certain GUIs rather than an autistic person who does not make it a habit to avoid math. I guess, that is the idiosyncrasy that is humanity, LOL.

The stupid@ss journalist that had to post an asinine, sarcastic Twitter remark at the expense of Ted Kaczynski's request of a rebuttal to his brother's erroneous mental illness claims FURTHER affirms that these journalists and the sheeple that assign credibility to their sorry@ss excuse of articles and reporting are the SCUM of the earth ... Their applications of statistics and their concepts of scientific methods are PATHETIC...

I'm baaAAAAACKKK!:)

FYI Nas, I started a Facebook account FOR ONLY the simple reason that most of my family lives 3000 miles away from me. I work a 7 to 3:30 job so it's already 6:30PM their time when I get home; not leaving much time for phone calls. I'll send you a link to my page in the next couple weeks.

I'm not using social media as a means of acquiring hundreds or even thousands of fake@ss 'friends', which seems to be the natural sheep-like propensity for typical users ... Just family and a few friends like you (i.e. REAL, dependable people. Not a bunch of egocentric, asinine narcissists that are addicted to selfies and who seem to be the sort of vaginal discharge offspring of people similar to Kim Kardashian or Daniel Tosh).

Anyway, I've got some aeroports for my Phantom Wedge enclosure; I'll post a pic of them on here sometime this week.

So I'm going to make interchangeable baffles for different subwoofers in my Phantom Wedge. The ports won't be the only thing that is interchangeable.

I'm so impressed by the RE Audio XX 12 D4's smooth yet immense bass output that I plan to eventually pick up two REA XX v2 12 D2s' come this December when I get raised up a pay grade. But I'm job hunting in the meantime; I've sorta grown to hate my current job plus I'm seriously underemployed. One thing I've noticed now is that with my experience I am more attractive to employers now. Opportunities in San Diego for CE are still relatively sparse so I've expanded my job search radius to include Orange County.

I would like to see a JLA W7 version 2 series at CES in January. That may happen, or it may very well not happen. I'd certainly love to see DC Audio and Digital Designs begin experimenting with nitrile butylene rubber surround. I would certainly love to have me some more subwoofers with Finite Element Analysis behind them.

Anyway, back to the new REs' ... I would like to sometime next year pick up a second JLA 1200/1v3 so I can run each 2 Ohm DVC sub to a 4 Ohm impedance for better efficiency and damping factor. The one TDK Genesys 15-220-1P230 should cover the RMS ampacity but the transient surges I am concerned about ... I have no idea what the crest or the surge capability is with my power supply. So I'm sorta entertaining the thought of acquiring another TDK GEN 15-220 with my tax return ... possibly ... We'll see how it goes.

Stay tuned.

Oh wow Kirk, I wish we lived closer then I would pay you to do all my handiwork. The way you've built and designed your enclosures looks amazing. I would LOVE to have an indoor setup like you have. It must sound amazing.

I tried to search for you on Facebook but couldn't find your details? Fyi, I have completed my install and will email you the pics but the LOC is giving LOTS of interference noise. I have been advised that an Audiocontrol lc2i (Line out control) should be able to fix my current audio problems but it doesn't have a remote line out with it, if you know of any high quality loc's then please let me know.

I have a really nice setup that's fitted properly and with high end kit and one silly item is spoiling it all.

Anyway, dude, would it be possible for you to make a video of the setup you've posted pics of above?

Chat soon,

Nas.

Hi, on occasion I get a 503 site error when I browse your site. Just a heads up, cheers

Hey,

I wanted to know if you created your own theater?

So as you can see much has transpired since the time I last posted in 2016.

I came to the realization that I would rather buy two RE Audio XX v2 12 D2s' rather than awaiting that pair of JL Audio 12W7v2-3s'. REA XX 12 is half the price of the current 12W7AE-3 and it has the nitrile butylene rubber surround that I want. I initially wanted the dual 2 ohm voice coil version because I thought I would need a second JLA 1200/1v3 and run each at 4 ohms. Well, as it turned out, I wired them up in 2 ohms series/parallel on the one JLA amp I have and the output was massive and admittedly too much for the mobile home at moderate volumes. That turned out to be a problem with running both the floorstanders and the sub off of the stereo receiver. The solution was to get a Yamaha WXC-50 pre-amplifier and use that as the subwoofer's volume source. It exceeded my expectations in that it has its own DAC that gives the signal to the amplifier tighter regulation; the result being musical punchy bass even at low volumes. I made the mistake of buying one of those big Stinger capacitors ... While the things sorta work I find that peoples descriptions of what they actually do to be accurate. They'll supply power on a transient for only seconds but are by no means a substitute for a big battery or alternator. I had followed the charging instructions, but there's really no way of keeping it charged as I usually turn the TDK Genesys 15-220 off when it is not use. So its inactive now; set aside. After my purchase of the pre-amplifier, I have no use for my line driver so that is inactive.

If I can describe my subwoofer install with the two RE Audio XX v2 12 D2s on the big JLA 1200/1v3, it would be musical and smoooth. That extra O was intentional. The Phantom Wedge utilizes a 55 degree inclined back that effectively deflects the initial sound wave propagating from the rear of the woofer's diaphragm and continues to ricochet the wave in a diamond pattern. Thus, no formation of standing waves that propagate back into the woofer's diaphragm causing superfluous oscillations marring the sound quality. The Phantom Wedge is everything I ever dreamed about in my goals of designing a system that is comparable to a movie theater with THX equipment installed in it. That and I think it gives JL Audio's Gotham a run for the money in sheer output. I called it the Phantom Wedge as my initial idea was to install two JL Audio 12W7v2-3s' in it. But they would be too expensive for the kind of income I make right now and so I would like to get the W7v2s' after I buy home with a decent sized basement (bass-ment LOL). I'd only ever buy them earlier in the rare event of JL Audio going out of business. Once I buy them though I would install a relay to alternate between the RE Audio XX v2 12 D2s' Phantom Wedge and the JL Audio 12W7v2-3s' Phantom Wedge with each on their own dedicated JLA 1200/1v3.

Audio aside, it was never my intention to start an Autistic Revolution with some of my derogatory posts on here, for if I did, I would windup like Okwonkwo in Chinua Achebe's Things Fall Apart. I, at least, can say for myself I attribute a perception that penetrates the bullsh*t, the societal hypocrisy, the societal dogma that encourages dogmatic conformity and the naive optimism in a better tomorrow. Stephen Hawking suggested humanity has 1000 years left on Earth. I thought, why didn't he say 100 years. Not too soon after, he did indeed say 100 years. And so you see, are we going to accomplish anything revolutionary in the next 100 years??? No, the answer in short is no. Humanity, principally neurotypicals with undiagnosed Narcissistic Personality Disorder such as J.P. Morgan, put humanity, put our fragile Earth on this rapid course of destruction. Interesting how one man, Sir Isaac Newton, predicted this collective asininity on humanity's part in the 20th and 21st century. We have, in effect, validated his 2060 Doomsday Prophesy be it the worsening global warming or the divisive vices we hold so dear as virtues such as our individual religions.

Anyway, enough said. While Car Review is dead or dying, my audio antics and shenanigans will live on in my You Tube channel, KirK's Home Car Audio.

This thread is officially finished.

You surely have a talent, you can change a simple thing into a useful stuff.
